To v1f/ZZ whom, it may concern: -I

le it known that LJESSE W.SUNDERLA.ND,

a citizen of the United States, residing at Chicago, in thecounty ofCook and State of Illi- 5 nois,'have invented a new and useful Improvement in'lVashing-ltlachines, of which Vthe fol-l lowing is aspecification.

My invention relates to an improvement in washing-machines of the classin which a' ro-4 tating cylinder having perforated `walls is .caused torotate within a stationary cylinder and' contains traveling disks,nsually perforated, which are caused automatically tom'ove towardand'away from each other to ede'ct a contained in the cylinderr.- l

In an apparatus loli this' character of .the

. kind to which my invention-more particularly relates therotatable'cylinderis caused to turn thereupon to turn in thereversedirection, said rotation andV reversal being edected throughA ,yabelt-shifting mechanism on the pulleys, .and it has been the practice tocause the rotation of the cylinders in the opposite directions,respectively, to produce thehlovementof the travelingdisks within thecylinder.

My object is to improve washinglnachines of this `character in general,andparticularly 3c to-cause the movement of the traveling disks 'to be'in a measure independent'of'the rotation of .the cylinder, while at thesame time causing both operations to-be accomplished from thesame powercontrolled by the'belt- 35-shifter. V l L ,In the drawings, Figure lis aplanscctional view on the line 2 2-ofjFig. 2 and viewed in 'uthedirection ofthe arro'w,.showingithe gen- I' eral construction of mydevice; Fig. 2, a view chine; fFg. 3, a vertical transverse sectiontaken on line'3 3 ot Figuilnnd viewed in the direction of the arrow,parts being brokenVv .away to illustrate details of the construction foftwo similar roller-hearing devicesemployed thorough washing andcleansing of the clothes in one direction a certain n'umberof times and"in end elevation, taken at the head ofthe mawhich would otherwisegbehidden from viewj Fig. 4, a broken end .elevatiompartly in secstion, thesection heingtaken on' line 4 4 ofljf `Fig. landqviewed" in' thedirection .Q fthe alf-j ger-rods Whichcarry the traveling disk-s witl1 55 in the cylinder; and Fig. 8, an enlarged'sectional view of a portionof the inner cylinder,

A represents the' outer cylinder, which 'is 6o .supported on legs A. 1

The-heads B are provided with central perforations t and formed withcentral inner recesses t', about the perforations t, and within whichare supported nests of roller-bear- 65. -ings C. v v

D is an inner or washing cylinder comprising end spiders s, havingcentral outward-'projecting trunnionss', which extend into the recesses#and carry the nests or roller-.bearings 7o` C.- The walls of the inner'cylinder D comprise perforatedv longitudinally-extending staves E, heldtogether at theiredges bylongitudinally-arranged brace-rods E'. Thebrace'- rods E are in the form of half tubes, as indi- 75 cated in Fig.5, provided at intervals with solid lugs E2, containing threaded socketsr. The Y lug portions E2 ot'- the brace-rods E presentl ,cesses thespidersare providediwi-th periphgo "eral cog-teeth s2.

Within the cylinder D 'are supported`the l spidersE F,ea ch carrying-aperforated platep.. The `spiders EF' have the circumferentialconfiguration ofv the cylinder D and are 93.

.adapted'to slide in the latter. The spider F at itscenter fits over theinner end cfa plnngerlrod G, and the spider F receives centrally theinner endof a plunger-rod G.- The rods G G areeach provided on onetfacewith a rack roo o', which is shown in the drawings aspresenting'the-ou'ter -.edge of each tooth within the circumferential'area vof the rod. AThe rods.. G G' extend-...through the trunnions s?and through the central apertures tn of the heads i3 B of the outercylinder. The spiders F F', though held to and carrying the plunger-rodsG G', `are rotatable thereon, this being accomplished by providinganannular groove 0' near the end ot'4 each plunger-rod, which groove isengaged by set-screws o2 passing through tlie'hubs of the spiders. Theheads l; B at opposite ends of the cylinder A carry, bolted thereto,supplemental heads I-I II', and lpivotally mounted upon the head H ishydraulicjack mechanism I, presently described. Tie-rods K extend fromone supplemental head H tothe other supplemental head ll", asillustrated in Fig. 1. Y

Supported in a suitable bracket L at one side of the head end'of themachine and extending to a corresponding bracket L at the foot end ofthe machine, is a horizontal shaft made of two independent sections M M.

Loosely surrounding the shaft-section M is a hollow shaft or sleeve M2.The shaft-section Y M is provided at itsouter end with a.' worm n and cnthe outer end portion of the sleeve M* is a worm m.. \At its outer endthe shaftsecton M is provided beyond-the bracket L with a worm m. Onthesleeve M2, in the position shown, is a pinion N, which meshes with apinion N', 'journaled on the bracket L, andthe pinion N extends at itsperiphery througha slot or opening in the outer casing A, and inturnmeshes with the cogs sion the spider s at the head of the machine.The shaft-section M4 carries, adjacent to` the bracket L a pinion N,which meshes with a Apinion N3, which in turn meshes with a pinion N4.The 'pinions N3 N are journaled upon the sides of the bracket L', andthepinion N4-extends at its periphery through an opening-.in the outercylinder A andmeshes with the cogs $2.011 the spider s at the foot endof the cylinder D. The sleeve M2 at its Vss p formed on thehead B,andillnstratedin Fig.

inner end carries a belt-pulley@ and the shaft-section M near its innerend carries a belt-pulley O Between 'the belt-pulleys O .O and coveringthe joints of the shaft-seetionsM' M is a pulley O", keyed to theshaftsection M'. Extending from the bracket L- to a supplemental bracketL, w ich forms one of the bearings of the shaft-se tions M,i's abe1t-shiftiug arm vP, having-the aperture l for the belt, and also the'socketedr end l',-to which 'is secured one; end -of 'a lever l. The

aperture! should be of a length approximating the width of the pulley0', and thedrivebelt employed should be of a width approxi-4 mating vthelength of said apertures The' lever I hasjthe Yeionga'ted'slot Za andhandle 2; .A worm-gear Q, jonrnaled on an armof the bracket Lqto meshwith the worm n on Vthe shaft-section MQ has'the.1eceentricpin Q., whichenters the' elongated slotl? in the lever worm-wheeiR, mounted upon ashaft'R',-extending'across the head of the cylinder and terminating atits opposite end'l in bearings The worm mls adapted to meshv with a,

4. Between the said bearings at the head B the shaft R carries a pinionS,said pinion meshing with the teeth o on the plunger-rod G. The shaft Ris so mounted in its bearings on the head 'B that it may vibrate toalimited-extent at its outer end .where it carries the worm-wheel R.Near its. outerl end the' shaft R' isjournaled in a bearing R?, sup#downward at its free end and disengages the worm-gear R from the worm m.At the '0p- -posite end of the machine the same construe-' tion ispresented--that is tosay, wi'th the wormm. there meshes the worm-gear R,(see Fig. 3,) the shaft Rf which carries a pinion corresponding with thepinion S, which enadjacent 'head B of the cylinder in a manner to permitvthe shaft to swing in its .bearing and'carry thefworm-gear R intovandont of 'gages the-teeth on the plunger-rod G". The shaft R4 isjonrnaled in the bearing on the Ilo-0 engagement with the worm 'm'.` Theshaft R4 is journaled adjacent to the worm-gear Riina bearing-collarkien, the upper end 'of ar'od.

k,f wl1ich at its lowJer end is pivotedupon a' pin k7 on a disk k. Thedisk is on the endof,

a rock-shaftk, journaled. in a bearing on one of thelegs of the machine,and carries a pin k7, eccentric withrelati'on to said shaft. Ex'-'tending between'and pivotaliy'connected at opposite ends tothe ins lck7 on therespective disks kk is a ro 10?, whereby. movement of the shaftk to raisfe or lower the worm-gear R is -Lm-parted to the shaft k andattendant parts, whereby the worm-gearR is thrown into and ont of' meshwith the worm m at the same time that the worm-gearis thrown into andout o'ffmesh withthe worm m. I

The hydraulic-jack mechanism comprises'a casing I, having a smoothinner.' face conform-v ing to the outer face of 'the' supplemental headH, The casing I is pivotally mounted at one end upon-an extension 4ofone of the tie-bars K. It may swing on said tie-bar-between ver'- ticalland horizontal positions,` and at its free .end it is formed into ahook I', whereby whenswnng tethejhoriwutal 4position it engages and'is'held rigidly-'in place yby thetie-bsr'K on the .opposite side ofthemachine. "In th'e .casing I, is a chamber i, containing a; piston i. Inthe, casing at :opposite sides of the said chamber are twopump-cylinders t" in' which 'work pistons upon'the ends of piston-redsi' a?, at their outer ends connected witlia pumplever. I', which ispil'voted upon. the casing belas tween the pistol-rods-i". Extendingfrom J the cylinders '1? to theend of the chamber 'i posed in thebranches of the said pipe are check-valves 116, which permit water topass freely through them to the cylinders, but prevent itsretrogression. In thepassages 4, beatween the pump-cylinders and4chamber i, are check-valves '512,'which prevent retrogress'ion of waterfrom the chamber to the cylinders under the suction action of thepump-pistons when water is drawnin-throngh, the check" valves i6. Asvalves for this purpose are provided in ail pumps or hydraulic jacks,it` is thought to be uunecessaryin the present connection to illustratethem by special view. In the end of .the chamber il is an outlet-port27, which communicates with a pipe is, which extends therefromthrolfi-gh the adjacent head B tothe interior of the cylinder A.Interposed in the pipe is is a valve '119, opened and closed by means ofthe hand-wheel'il". The sections of the pipes 'i5 c adjacent to thecasing I- are of flexible material and offer no obf stacle to theswinging of theV casing between its vertical and horizontal positions.

- In the supplemental headH, registering on one side with the opening tand atits cppoJ site vside with the chamber' ,lwhen the casing I isinthe horizontal position, is an opening h of a diameter slightlyexceeding the diame'i' ter of the' chamber; z'. v The pistoni isprevented from. covering-the ports in the .chambert by alpin il, carriedby the piston', which strikes ,the linner fend of the chamber when thepiston is moved inward. 'j It is to be understood that during thewashing operation,

presently described, the hydraulic jack' is swung-to the verticalposition to permit free reciprocation of the plunger-rod G, and when.the wringing operation :is to take place theplunger-rod is moved inwardas far as it will go underthe action of the pinion'S, operated from theworm m, at. which time its outer end just clears the inner face'of thehydraulic jack when the latter isswnhg down tothe `horizontal A plane.Wat'enpumped into the chamber lagainst the piston 'i' forces; the 'lat-vJterfoiitwardjinto the -op'eu'ing h and against -`the` outer end of. theplunger-rod G. The plunger-rod G moves through an opening g -in thelsupplemental headH, and when at the inward limit of its movement underthe action of the pinion on the shaft R4 its outer end has passed inwardthrough'the opening g to a po-v sition between the supplemental head Hand adjacent head B. lleivoted upon `a bolt g', adjajcen't tothe openingg, are one or more' stopplates g2, which maybe swungjrcm aposiltiefn'outof the path of the outer end ofthe pl unger-rod-.G to a position acrossthe path 4ol' thelatt'er., 'As hereinafter eX'plained,-.when v 65 v itis desired to perform'l thewringin-g opera'- tion the'pl ger-'rods G G-are movedv to their 'jinw'ard limits and oneor more of-the'plates souter end-of the latter from the inner face of g3, are swung across thepath ot. the plunger?v rod G', depending upon the. distance of the A #ofthe supplemental head I-I. This prevents the -said plunger-rod frombeing forced outward by -pressure from the rod G under the action ofthehydraulic .j ack.

. The operation vis a follows: Thelhydraulic `7 5 -jack I beingturned onits pivot tothe vertical plane to' vuncover the opening'h' through thesupplemental head H and the linternal traveling spidersF F beinginthe'position indicated in Fig. 1, the-belt is shifted by hand 8o,through the mediumof the lever l2 to overlap the pulley O, while stillretaining its grip upon the pulley O2. Pressure is exerted upon one ofthepedals 7a4 to move the .worm-gears'R R3 into meshV with the worms m,m', respectively. When the 'machineis started, the beltV rotates thepulleys O O2.. '.lhro'ughthe pulley O the' sleeve M2 and pinion Narerrot'atedto rotate the pinion N and turnfthe cylinder D on litstrunnions. The. rotation of the cylinder D through its engagement at theopposite end with the pinion N4 rotates the latter-,the pinion N3, andpinion N2 on the' shaft M The rotation of the pulley O4 producesrotation of the shaft M and itsworm-m. It' will be un- 95 derstood,therefore, that in the rotation of the pulleys O O'J the shaft M and itsworm 'n and'the sleeveM2 and itsworm fm are allro- 'ta'tedimpartingrotation to the cylinder D,

Athat of the shaft Mand sleeve M2. YDuring this rotation the 'worm mturns the'worm-gear [o5 R, -shaft R', andpinion S to causethe'plunger-'rod G and spder'E'tofmo'v'e inthe out ward direction; andthe engagement ot the worm-gear R8 with the worm m causes it and` theshaft R4 toturn in thedirection for mov- 'r 1o ing the plunger-rodfandspider'F inthe outward. direction'. The plateg2, which inv Fig..1 is'shown in the path of the. endof the- 'pl-unger-rodG, must be turnedaside before thelcom'mencement of the operation.- r[,he ror1.5 tation ofthe shaft'M, and consequent turning .of its worm n,rotates theworm-wheel Q, and as the spiders F11", near -the opposite endsof thecylinder,4 the pinQ engages one len'd ofthe 'slot l"l o fthe lever 2 andpushes 12o lthe latter inv the direction to slidethe beltshifting bar Pto the position wherein the belt engagesl the pulleys O2 and O. The en-LAgagement ot' the beltwith the pulleyO' projduces immediate reversal ofsaid pulley and 125 theshaft M, whereby through the gears:NNs Nffstherotation of the cylinderD isreversed, an'd'through the engagement of thecylinder with the pinion N'-` a'nd throughA the-latter with the pinion Nthe rotation of the sleeve w3c M? and attendant 'parts is' reverf'ed.lTherefore' as soon as .the belt is shippedfrom. the'jpulley O tothepulley Of thev plungerl rode G G are moved- Ain the direction ofeachother. When the spiders arrive at the' l 4 position indicated inFig. 1, their movement iiO is again reversed and the operation will becontinuous. '.lheinward and outward playof vdrive-belt, the water iswithdrawn -from the cylinder A and the movement of themechauismdescribed is'stopped when the spiders are both at their innermostposition indicated spider F.

in Fig. l. As a preliminary to performing Vthe wringing operation, -th'erock-shaft :.3 is

turned by'pressure upon one of the pedals 1" to lower thewormgears R Rsout ot'y ,engagement with the worm m, m', whereby move: ment of theplunger-rods G G' is'stoppe'd. One ormore stop-plates q2-are then swungacross the path of the plunger-rod G.

The pump-lever 12 isthenoperated to force-water into the chamber 1against the endof the piston i' and force the l'atter with theplungerrod G and spider Fin the direction of the By this means greatpressureis exerted between the plates p, and the bar G is prevented fromyielding by the stop plate or plates g2. Thepower-shaft frontiWhiehthemachine isoperated may be provided, as is"` common in all such cases,with fast andlos pulleys and belt-shipping mechanism, all of which itis'not thought necessary to illustrate.

1f desired, the belt-shipping mechanism may wringing'mechanism isbrought into action.

lt is better, however, to permit the cylinderV 'D and disks ,1.2 torotate, as described, while the wringing operation is being performed,because the motion tends to discharge the water by centrifugal force asit-issqueezed. out of the washed .articles by the .hydraulic jack. `fhenthe wringing operation is complet'ed, the -workingof the pump isstopped.A

and the valve i. is opened by means of the .hand-wheel t1", causing thewater in the chamber i to 'flow ont through the pipe i, intothe baseofthe cylinder A. The hydraulic jack is then swung tothe vertical plane,thestop plate or plates g2 are turned out of the way,` r and therock-shaft L is'turne'd to cause. the; "worm-gears R R8 to-mesh withtheworms m mi.; This action causes the'plunger-rodsto- 4be moved in thedirection of the ends of, the
